An omnidirectional antenna, for example, is usually a vertical polarized antenna. Directional antennas focus the RF energy in a particular direction. ... For directional antennas, the lobes are pushed in a certain direction and little energy is there on the back side of the antenna.

Are omni directional TV antennas any good?
Omnidirectional antennas also pull from 3 and 4G signals, and have overall better performance than a directional antenna. You have a complete, 360 degree reception field, which allows for good reception from a variety of directions.
What is meant by omni directional antenna?
In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis (elevation angle), declining to zero on the axis.
What are the advantages of a directional antenna?
A directional antenna or beam antenna is an antenna which radiates or receives greater power in specific directions allowing increased performance and reduced interference from unwanted sources.
What is the best omni-directional antenna?
Best Omnidirectional Outdoor TV Antenna

Is directional or omnidirectional antenna better?
An omnidirectional antenna generally works well in areas where the cellular signal available is good - reflected from nearby objects, either naturally or man. ... This directional antenna is recommended far more often than an omni-directional antenna as it has double the gain.
What does Omni mean?
a combining form meaning “all,” used in the formation of compound words: omnifarious; omnipotence; omniscient.
Is a higher dBi Antenna better?
The higher the dBi number of the antenna, the higher the gain, but less of a broad field pattern, meaning that the signal strength will go further but in a narrower direction, as illustrated in the diagram below.
Is higher antenna gain better?
On an open and flat highway, a high gain antenna will be better… 3 dB, 6 dB, etc. If your desired coverage area is hilly then a ¼ wave omnidirectional antenna will be better. The other type of gain is directional and is important for base stations.
Which antenna has highest gain?
dBd - "decibels relative to a dipole antenna". Note that a half-wavelength dipole antenna has a gain of 2.15 dBi. Hence, 7.85 dBd means the peak gain is 7.85 dB higher than a dipole antenna; this is 10 dB higher than an isotropic antenna.
Does antenna gain affect reception?
Higher gain antennas can increase your reception (it will be directional and match the transmission pattern of that specific antenna.). 2. You are still at the mercy of the weakest transmitting power (distance).
Is a directional antenna useful for mobile phones?
Without any additional “intelligence” directional antennas are not useful in standard mobile phones as users may not want to direct the phone to a certain antenna. Users move, rotate, flip the phones etc. Phones are in bags, pockets, … while operated hands-free.
